Guralp Systems CMG-DCM build <10,000 - Manual (Page 35)

Acquisition Modules and Platinum Firmware Platinum Overview
4.2.3 Navigation instructions in the manual
In this manual, instructions on how to reach a particular screen are displayed
like this:
Configuration → Interfaces → eth0 - Primary wired network interface
In this example, to reach the page indicated, scroll to the “Configuration”
section of the main menu then click on the “Interfaces” link". From the list
that appears in the main frame, click on the “eth0 - Primary wired network
interface” link.
In some cases there are two possible paths to a particular screen. Both are
shown in the manual.
4.3 Using the command-line configuration system
All of the configuration facilities available under the “All options” item (in the
main menu of the web interface) are also available from a text-based GUI tool
called gconfig (Güralp Configurator). This can be accessed either by using a
serial link or, over the network, by using ssh.
Connection via a serial link is discussed in section 3.3 on page 30 and
connecting over Ethernet is described in section 3.2 on page 20. The use of
ssh is covered in section 3.2.5 on page 27.
4.3.1 Using graphical interfaces from the command line
Some Platinum applications use a system called “ncurses”, which allows
graphical interfaces to be implemented on text-only terminals. This requires
the applications to know the type of terminal from which they are being
accessed. The terminal type is stored in an environment variable called TERM,
which is queried with the command
eam999 ~ # echo $TERM
vt100
eam999 ~ #
(note the use of the $ sign when accessing the value of this variable) and set
with the command
eam999 ~ #: export TERM=vt100
No spaces should be used around the '=' sign.
Platinum is aware of around thirty different terminal types and uses the
“terminfo” system to support them (so you can add your own types, if you
need). Files describing each terminal type are stored under the directory
(folder) /usr/share/terminfo in sub-directories named after the initial
letter of the terminal name.
Some settings for specific applications are given in the following table.
